DETAILED DESCRIPTION OF THE INVENTION

Provided herein are eyeglass assemblies comprising bridge frames, temple lugs or lens receiving portions with unique capture features to retain lenses having lens tabs configured to insert and become removably captured in the bridge frames, temple lugs or lens receiving portions. The lens tabs protrude through the lens tab thru-holes of the bridge frames, temple lugs or lens receiving portions to provide a visual and tactile confirmation of lens capture.

The assemblies provide a simpler way for wearers to independently replace or switch lenses in their eyeglass assemblies when in need of repair, or to exchange the lenses to accommodate another need.

The features described for the eyeglasses disclosed herein are relevant to eyeglasses intended for or designed for athletes, athletic competition and casual sporting wear. Frequently, individuals involved in outdoor activities such as tennis, golf, biking, running or triathlons, will have a need for rugged, yet fashionable eyewear that is customizable for their individual needs. However, as a matter of convenience, individuals do not want to carry around multiple pairs of eyeglasses as spares, or extra glasses with different lenses for things like sunglasses or reading prescriptions.

Prior solutions have included bulky overlay glasses to provide some form of anterior and/or lateral shading that rest over the prescription lenses worn by an individual. These are often looked upon as not being very flattering or fashionable.

Alternatively, others have provided “clip-on” overlay lenses to provide for limited convertibility of prescription lenses to prescription sun glasses. However, those lenses also frequently have a separate frame, with an attachment means for securing to the original frames and lenses. Unfortunately, the attachment means for “clip-on” overlay lenses often involves a clip that attaches over the frame and often onto the lenses of the prescription glasses, oftentimes scratching the prescription lenses over time.

The inventors herein have devised a solution that allows a wearer to conveniently remove and replace just the lens or lenses, when the need to do so arises. The attachment tabs on the lenses and the receiving means in the frames, temple lugs or lens receiving portions provide both a tactile means for assuring the secure attachment (or removal) of the lens from the frame, temple lugs or lens receiving portions, as well as a clear visual indication.

Further still, the replacement lenses are now provided in different lens heights, and in some cases, in different widths to provide the wearer with customizable sizing and added eye protection from wind or flying debris.

Still further, alternative bridge frame and/or rocker frame designs provide the wearer with variable rigidity and strength in each eyewear design.

Replacement lenses and frames can be easily carried in either a thin and secure case for just lenses that need not be as a bulky as the eyeglass case for the glasses themselves. Alternately the eyeglass case can be configured to carry one or more spare lenses and frames. Replacement lenses can include duplicate lenses in the event of scratches, or alternate lenses having different tinting shades for different sun conditions, or with alternate prescription requirements for a left eye, a right eye, or both eyes, or to provide an anti-reflective treatment; a photochromic treatment; a polarized treatment; a tinting treatment; a scratch resistant treatment; a mirror coating treatment; an anti-fog coating treatment; a hydro-phobic coating treatment; an oleo-phobic coating treatment; or any combination of the coatings or treatments described herein.

In an effort to provide both practical and stylish options, the inventors have devised a plurality of variations of frame and lens combinations comprising full-rimmed, semi-rimmed, rimless, and twin or dual semi-rimmed eyeglasses, each having the unique attachment mechanism to be described in further detail below. Further, the full rimmed and semi-rimmed versions have interchangeable frame and lens components and, at a minimum, the multiple eyewear variations comprise interchangeable lenses.

As used herein, a single lens configuration design refers to a streamline design style comprising properties configured to increase the aerodynamic properties of the wearer's face. Styles of this type are commonly referred to as “wrap” style, or alternately are referred to as “shield” style sport glasses.

The “wrap-around” frame styles commonly have lenses that cover a large portion of the area around a wearer's eyes, intended to maximize field of view and minimize or prevent UV rays from penetrating the wearer's eyes through the side. Additionally the “wrap-around” frame style further protects from excessive amounts of wind and provides added protection from flying objects such as dirt, gravel, sand, water, snow and other fragments Athletes participating in running, cycling, golfing, driving, shooting, water, snow and beach activities often prefer this style. Variations of the “wrap” frame style are also provided with adjustable temple arms that are spring-loaded to help them stay on the wearer's face during vigorous activities. A unique version of adjustable spring-loaded temple arms is also provided for each of the eyewear versions described herein.

Alternately, the “shield” frame styles commonly have even larger lenses that cover most or all of the area around a wearer's eyes and additional areas above below and beside the eye sockets. These styles are also intended to maximize field of view and minimize or prevent UV rays from penetrating the wearer's eyes through the side. Athletes participating in running, biking and shooting activities often prefer this style because it offers a greater field of vision and provides added protection from road debris that is often thrown up from tires or shoes used by nearby athletes. Variations of the “shield” frame style are also provided with adjustable temple arms that are spring-loaded to help them stay on the wearer's face during vigorous activities like triathlons and IronMan® athletic competitions, as well as other endurance activities.

In some embodiments, either the “wrap” style, or the “shield” style sport glasses are configurable with or without a frame rim to provide an individually desired amount of support, stiffness and/or amount of protection to the single lens.

In some embodiments, the unitary or molded split nose bridge insert 150, 250 comprises: coupler portion 154, 254; and a pad linker arch 156, 256, wherein the coupler portion is configured to releasably attach to the central notched region 102 of the single lens 101, and wherein the pad linker arch 156, 256, is configured to be posteriorly offset from the coupler portion and is further configured to straddle the bridge of a nose of the wearer.

In some embodiments, a split nose bridge insert 150, 250 is a molded piece that comprises two or more materials. In some embodiments, the coupler portion 154, 254 and the pad linker arch 156, 256, are each molded of the same material. In some embodiments, the coupler portion comprises a first material and the pad linker arch comprises a second material, and the first material and the second material are different materials.

In some embodiments, the coupler portion 154, 254 and the pad linker arch 156, 256, are each molded of the same material having the same durometer. In some embodiments, the coupler portion comprises a first material having a first durometer, and the pad linker arch comprises the first material comprising a second durometer, and the first durometer and the second durometer are different. In some embodiments, the coupler portion comprises a first material having a first durometer, and the pad linker arch comprises the second material comprising the first durometer. In some embodiments, the coupler portion comprises a first material having a first durometer, and the pad linker arch comprises the second material comprising a second durometer, wherein the first durometer and the second durometer are different, and the first material and the second material are different materials. As used herein, the term durometer refers to a measurement of the hardness of a material. Hardness is defined as a material's resistance to permanent indentation.

In some embodiments, the durometer of the coupler portion 154, 254 is harder (higher) than the durometer of the pad linker arch 156, 256. A harder or tougher or higher durometer would provide a more secure attachment means between the lens and the nose bridge, whereas a softer durometer material would provide softer cushioning over the bridge of the nose of the wearer.

In some embodiments the durometer of the coupler portion is within a range from about Shore 60A to about Shore 100A. In some embodiments the durometer of the pad linker arch is within a range from about Shore 20A to about Shore 70A.

In some embodiments, the coupler portion and the pad linker arch of the molded split nose bridge insert 150 are integral with each other, such as illustrated in FIGS. 15A and 15B. This is often achieved by a molding process that molds the coupler portion and pad linker arch as a single piece. In some embodiments the durometer of the coupler portion and the pad linker arch is within a range from about Shore 40A to about Shore 80A when they are molded together as a single integral unit comprising a single material. In some embodiments the durometer of the coupler portion is within a range from about Shore 60A to about Shore 100A and the durometer of the pad linker arch is within a range from about Shore 20A to about Shore 70A when they are molded together as a single integral unit, but comprising materials of different durometers. Those materials can be the same, having only different durometers, or they can be different materials entirely.

In some embodiments, the coupler portion 154, 254 and the pad linker arch 156, 256 of the molded split nose bridge insert 150, 250 are assembled after molding, such as illustrated in FIG. 15C. In some embodiments, the coupler portion 154 is further with one or more attachment features, comprising slots, grooves or slits, in mating alignment with one or more protrusions or tabs of the pad linker arch or of the nose pads themselves, such that the first portion and the second portion can be accurately aligned and assembled together in either a releasable or permanent fashion. In some embodiments, the coupler portion is further configured with one or more attachment features, comprising protrusions 172, 272, or tabs, in mating alignment with one or more cooperating attachment features, comprising slots, grooves, or slits 174, 274 of the pad linker arch, the linking arch, or of the nose pads, such that the first portion and the second portion can be accurately aligned and assembled together in either a releasable or permanent fashion. The attachment features of the coupler portion; and the attachment features of the pad linker arch are aligned and assembled together in either a releasable or permanent fashion.

In some embodiments, the formation (by molding or another manner) of any portion of either the coupler portion or the pad linker arch will in some embodiments, precede permanent attachment to one or more other portions of the molded split nose bridge insert 150, 250.

In some embodiments, the first medial side 162, 262 of the first nose pad 158, 258 and the second medial side 168, 268 of the second nose pad 164, 264 extending from the second nose bridge portion 156, 256 comprise one or more textured gripping surfaces 170, 270 to further stabilize the eyeglasses over the bridge of the nose, lateral cartilages, lesser alar cartilages, supra alar creases, and/or dense connective tissue above the nostrils of the wearer, or a combination thereof. This is particularly helpful for humid or sweaty conditions to reduce or eliminate slipping of the eyeglasses as compared to smooth and/or higher durometer pad surfaces. The textured surfaces resemble those of the foot/toe pads on a gecko. Geckos have highly specialized toe pads. This enables them, much to the amazement of human onlookers, to climb vertical surfaces. They can even cross ceilings. Geckos can stick to walls and ceilings because of the attractive nature of intermolecular van der Waals forces. Van der Waals forces include attractions and repulsions between atoms, molecules, and surfaces, as well as other intermolecular forces.

To further augment the gripping capability of the textured gripping surface 170, 270 of the split nose bridge insert, the textured gripping surface comprises a modified gecko texture pattern that is similar to but different from that of a gecko's textured toe pads. Similar to the gecko's toe pad patterns, the textured surface of the textured gripping surface 170, 270 of the split nose bridge insert 150/250, and the temple textured surface 192 a, 192 b, 292 a, 292 b, 392 a, 392 b described elsewhere herein, have irregular outgrowth ridge patterns that act in a similar manner to the footpads and toe pads of the gecko, to improve adhesion of the medial sides 162, 168, 262, 268 of the nose pads 158, 258, 164, 264.

In some embodiments of the single lens semi-rimmed design, the variable shapes include different radii of curvature of the lens. In some embodiments, the radius of curvature is about 7.0 Base Curve (referred to as “Base” elsewhere herein) in the horizontal direction, by about 4.0 Base Curve in the vertical direction relative to a wearer's eye.

As used herein, the term Base, Base Curve or Base Curve Radius, or simply base curve (abbreviated BCR or BC) refers to the flatter curvature of a lens (typically) measured in diopters (D) on the front side of a spectacle lens in optometry. Alternatively, on a contact lens, the base curve is the radius of the sphere of the back of the lens that the prescription describes, sometimes referred to as the back central optic radius (abbreviated BCOR), (the lower the number, the steeper the curve of the cornea and the lens, the higher the number, the flatter the curve of the cornea and the tens). Typical values for a contact lens are from 8.0 mm to 10.0 mm. However the full range of base curve is much greater and is often described in a range of about 0.50 D to about 10.00 D. This number is important in order to allow the contact lens to fit well to the wearer's cornea for comfort, to facilitate tear exchange, and to allow oxygen transmission. Manufacturers typically produce a series of semi-finished lens blanks, each with its own base curve. This “base curve series” is a system of lens blanks that increases incrementally in surface power (e.g., +0.50 D, +2.00 D, +4.00 D, and so on). Each base curve in the series is used for producing a small range of prescriptions, as specified by the manufacturer. Consequently, the more base curves available in the series, the broader the prescription range of the product. Manufacturers make base curve selection charts available that provide the recommended prescription ranges for each base curve in the series. A typical base curve selection chart is illustrated below:

Typical Base Curve Selection Chart Power Range Base Curve +8.00 D to +4.75 D 10.00 D  +2.25 D to +4.50 D 8.00 D  +2.00 D to −2.00 D 6.00 D −2.25 D to −4.00 D 4.00 D −4.25 D to −7.00 D 2.50 D  −7.25 D to −12.00 D 0.50 D

Further still, in this application, the term base curve has been extended to include the radius of the frame that holds the spectacle lens(es) and is also used to describe the relative “fit” of the frame on a wearer's face and head.

In some embodiments, the radii of curvature in the horizontal and/or vertical direction relative to the wearer's eye is from about 3.0 Base to about 8.0 Base, from about 3.5 Base to about 7.5 Base, from about 4.0 Base to about 7.0 Base, from about 4.5 Base to about 6.5 Base, from about 5.0 Base to about 6.0 Base, from about 5.5 Base to about 5.5 Base, from about 6.0 Base to about 5.0 Base, from about 6.5 Base to about 4.5 Base, from about 7.0 Base to about 4.0 Base, from about 7.5 Base to about 3.5 Base, from about 8.0 Base to about 3.0 Base, from about 8.5 Base to about 2.5 Base, from about 9.0 Base to about 2.0 Base, from about 9.5 Base to about 1.5 Base, from about 10.0 Base to about 1.0 Base, from about 10.5 Base to about 0.5 Base, or from about 11.0 Base to about 0.0 Base.

In some embodiments, the first medial side 162 of the first nose pad 158 and the second medial side 168 of the second nose pad 164 extending from the second nose bridge portion 156, 256 comprise one or more textured gripping surfaces 170, 270 to further stabilize the eyeglasses over the bridge of the nose, lateral cartilages, lesser alar cartilages, supra alar creases, and/or dense connective tissue above the nostrils of the wearer or a combination thereof. This is particularly helpful for humid or sweaty conditions to reduce or eliminate slipping of the eyeglasses as compared to smooth and/or higher durometer pad surfaces To further augment the gripping capability of the textured gripping surface 170, 270 of the split nose bridge insert, the textured gripping surface comprises a modified gecko-like texture pattern that is engineered to be similar to, but different from, that of a gecko's textured toe pads, as illustrated in FIG. 23.

In nature, the majority of gecko species have adhesive toe pads that allow them to adhere to most surfaces without the use of liquids or surface tension. The spatula-shaped setae arranged in lamellae on gecko footpads enable attractive van der Waals' forces between the β-keratin lamellae/setae/spatulae structures and the surface. In biology, setae /′si:ti:/ (singular seta /′si:t

′; from the Latin word for “bristle”) are any of a number of different bristle- or hair-like structures on living organisms. In surface anatomy, a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. Aside from respiratory organs, they appear in the traction surfaces of geckos. The pads on a gecko's feet are small hair-like processes that play a role in the animal's ability to cling to vertical surfaces. The micrometer-scale setae branch into nanometer-scale projections called spatulae.

Similar, but alternative to the gecko's foot pad patterns, the textured surface of the textured gripping surface 170, 270 of the split nose bridge insert 150/250, and the temple textured surface 192 a, 192 b, 292 a, 292 b, 392 a, 392 b, have irregular outgrowth ridge patterns, that act in a similar manner to the footpads of the gecko, to improve adhesion of the medial sides 162, 168, 262, 268 of the nose pads 158, 258, 164, 264.
